Kevin Wilson's "Tunneling to the Center of the Earth," from Ecco, has just been released. This is for me an event. Every once in a while a book of stories comes out that will seem, during the reading, just too good to finish. I close the book, hold the spine in one hand and feel happy about what's left to read. I've read enough of "Tunneling" elsewhere to know that it's going to be just that kind of book.
